Python is an object-oriented programming language that allows the user to create an object as an element of a computational domain. This kind of paradigm can represent real-world entities.Mutable and immutable objects are handled differently in Python. Immutable objects are quicker to access and are expensive to change because it involves the creation of a copy. Whereas mutable objects are easy to change. The use of mutable objects is recommended when there is a need to change the size or content of the object.The function gc.get_objects() will not find all objects, e.g. numpy arrays will not be found. import numpy as np import gc a = np.random.rand(100) objects = gc.get_objects() print(any[x is a for x in objects]) # will not find the numpy array You will need a function that expands all objects, as explained hereObject-oriented programming has some advantages over other design patterns. Development is faster and cheaper, with better software maintainability. This, in turn, leads to higher-quality software, which is also extensible with new methods and attributes. The learning curve is, however, steeper. The concept may be too complex for beginners.Being afraid of large objects can be challenging, but various treatments can help.
